LitePCIe, vendored PRISTINE. Never edit anything in this directory.

upstream: https://github.com/enjoy-digital/litepcie
tag:      2026.08
commit:   671aa895acdb96015ce841cc730579c0f2b678a3

Only the files the driver build uses are vendored: software/kernel/main.c, config.h, flags.h and
litepcie.h, plus LICENSE. Upstream's software/kernel/litex.h is left out because nothing here
includes it, and it is the one GPL-2.0 file in that directory.

Our changes live in src/fpga/driver/patches/ and are applied at build time into a
separate build directory. `git diff` here should always be empty.
